ISSUE:

Some 2005-2007 F-Super Duty vehicles with a long wheelbase of 156″, 158″, or 172″ (396, 401, or 437 cm) and equipped with a trailer hitch may exhibit a vehicle vertical vibration, often described as “hopping”, on smooth or coarse road surfaces in the 42-48 MPH (68-77 Km/h) speed range. Although this behavior is considered normal for an over 8500 GVW truck, some customers may be sensitive to the concern.

ACTION:

To improve the 42-48 MPH (68-77 Km/h) vertical vibration, follow the instruction sheet included in the Damper Service Kit.

NOTE:

THE INSTALLATION OF THIS DAMPER WILL NOT IMPROVE RIDE ON SEGMENTED CONCRETE HIGHWAYS, STEERING WHEEL VIBRATION/SHIMMY, OR GENERAL HARSH RIDE CONCERNS.
